All metadata (title of the article, full name and full title of places of work of each author) should be duplicated in English.
The pdf-files of the Russian and English versions of the published article are sent to the e-mail address, specified by the authors.
5. The journal is published in Russian language, its translation into English language is published under the title "Differencial'nye uravneniya". The indispensable condition for publication is the conclusion of contracts with the publishers of Russian and English versions of the journal.
After the article is accepted for publication, the completed and signed contracts with all co-authors are sent to: deq@cs.msu.ru.

II. REQUIREMENTS TO EXECUTION OF WORKS
1. The electronic version of the article should be prepared in the publishing system LaTeX according to the sample, located at the journal's website (files Sample (DOScp866).tex and Sample(WINcp1251).tex differ only in encoding).
It is forbidden to useproprietary style files, to enter overriding of the standard LaTeX commands \def, \newcommand, \renewcommand andproprietary ambient \newtheorem, \newenvironment for theorems, lemmas, definitions and so on.
2. The length of the article should not exceed 20 journal pages (page parameters see in the sample), and the length of brief communication should not exceed 5 pages. The big volume of the article is allowed on an individual basis, by the decision of the editorial board.
3. It is necessary to indicate the column of the journal to which the article is related (ordinary differential equations, partial differential equations, integral equations, integral and integro-differential equations, control theory, numerical methods, finite difference equations, brief communication), and the UDC index to which the content of the article corresponds (if the article corresponds to several indices, all of them should be indicated according to the rules of compilation of complex indices).
4. The title of the article should accurately reflect the main topic of the research.
The text of the article should be scrupulously edited and verified by the authors, and its results should be formulated in the form of accurate statements (theorems, lemmas, results, etc.) accompanied by rigorous mathematical proofs.
5. After the UDC, the title of the article and the surname of the author(s), an abstract with the volume of up to 15 lines is provided, containing a statement of the main results (without references to the text of the article or list of references, cumbersome formulas, undeciphered abbreviations and repetition of the text from introduction).
6. An article may contain no more than 5 illustrations (including parts of illustration with separate signatures). Each illustration is provided as a separate graphic file in eps format.

Figures, tables and diagrams are included directly in the text of the article.
7. Numbered formulas are included in a separate line on center, the formula number is placed at the right edge of the page. If the formula has several lines, then the number is placed at its last line. Numeration of formulas can be performed using the \eqno command. Automatic numeration of formulas using the {equation} procedure is welcomed. Moreover, authors must ensure the uniqueness of proprietary labels in relation to the labels of the authors of other articles from the journal number, using several initial letters of the surname of the first author in the label name.
Only those formulas which are referenced in the article should be numbered.
8. The formulization of statements (theorems, lemmas, results, etc.) is typed in italic \textit.
9. Fractions in formulas, not allocated in separate lines, as well as multilevel fractions in formulas, allocated in a separate line, should be written with a slash sign or with the usage of negative indicators.
10. The mathematical symbols lim, sup, ln, sin, Re, Im, etc. and the numeral 0 (zero) are typed in Roman font \lim, \sup, \ln, \sin, \mathrm{Re},\mathrm{Im}, etc. An exponential function with a complex argument should be written as the form of exp(...) or exp{...}.
11. The list of references is compiled in the order of reference of literary sources in the text of the paper and should contain only those sources, referenced in the paper. The total number of literary sources should not exceed 30.
In periodicals it is necessary to indicate the name of the journal, year, volume, number and pages. In references to monographs, pages (e.g., [1, p. 30]) or chapters and paragraphs (e.g., [1, Ch. 2, § 3]) must be provided after the serial number. References to unpublished works (except for dissertations) are not allowed.
In case of citation, the material should be cited only in the original language.
Group references should be avoided. All sources should be in public domain, it is preferable to indicate DOI (if available).
If in the course of work on text inLaTeX the support of bibliography{thebibliography}is used, then after completion of work on the article and compilation of short list of literature, the automatic numeration of list of references should be replaced by \cite manual numeration in the text. The list of references is organized using the \lit command. Its definition and examples of usage are provided in the abovementioned in art.1 of tex-file of the example of print design of article.
12. At the end of the article, the authors at their discretion can place acknowledgements to colleagues or supervisors and in special cases to reviewers, as well as indicate the sources of financial support for the research (grants, state programs, projects, sponsorship, etc.).
13. It is not recommended to make the final text composition: use additional vertical or horizontal spaces in the text or between values in formulas, get rid of small line overflows with the usage of forced hyphenation, etc.
14. Return of an article to the author for revision does not mean that it is approved for printing. The author should send the revised version of the article to the editorial office together with a reply to all the reviewer's comments and list of corrections. By decision of the Editorial Board, the article may be sent for additional review.
The Editorial Board reserves the right to reduce and edit the materials, intended for publication.
